Hey guy, I was thinking about doing some changing with my exhast. I have already cut the muffle off and installed a magnaflow one. I was think of getting the GM manifold and then leaving the rest of my piping. What do you guys think? I want a clean flow, no bottle necking......

 

no!!

 

eh, just get the zzp header/ downpipe combo

 

I'm selling my GMPP Header, if you are interested.

 

why are you selling it ?

 

Vibrant all the way

 

I'm selling it because I am getting a much larger one... in preparation for the TVS that I'll be buying later.

 

Changing out the header is such a pain in the ass that if your going to do it at least get a completely aftermarket one, something like the ZZP shorty header (not picking that one out, just what poped into my head hehe). I just spent 2-3 hours changing mine out and I already had the DP off the car and had the car up on jack stands. I can't see taking that much time to install a *slightly* ported version of my stock manifold.


If your looking to eliminate bottle necks the DP is a huge one, a mid-length header/dp combo (you can get them with out without high flow cats) is the way I would go if your already looking at putting a manifold on.

 

agreed.

 

do you guys think that this would effect my warentee???

 

I will second this.

 

If you get the GMPP, then it will affect it in no way, what so ever. Other brands... it all depends on the dealership and how big of dick heads they wanna be.
